Abstract
Description
マイカ、タルク、シリコーンエマルジョン等、離型剤としての必要成分があらかじめ混合されている市販のタイヤ用内面離型剤(松本油脂製薬株式会社製「RA−365P」)47質量部を水48質量部に混合溶解させ、離型剤の黒色化目的に、着色剤としてカーボンブラック(三菱化学株式会社製「三菱カーボンブラックMA−600」)を5質量部加え、ラボスケールのインライン型のローター/ステーター式せん断攪拌機(SILVERSON社製「ハイシアーミキサー モデルL4RT」)を用いて、均一に溶解分散し離型剤を調製した。攪拌機の回転数は6000rpmとし、処理時間は表1の通りとした。また、比較例4では、冷却装置を作動させず、それ以外の例では、リザーバータンク及び循環路に設けた冷却装置を作動させて、冷却しながら撹拌した。なお、比較例5では、撹拌に、従来の一般的なプロペラ攪拌機(回転数=300rpm)を用いた。撹拌処理後の各離型剤の液温を表1に示す。
得られた離型剤について、分散質の平均粒子径と、粘度を測定した。また、各離型剤を用いて、分散安定性、スプレーガンの詰まり性、乾燥性を評価した。各測定・評価方法は以下の通りである。
Claims (3)
- タイヤ加硫成形に際して生タイヤ内面に塗布される離型剤であって、
